How do we know that God is going to save His people?

The assurance of salvation comes from God's character and His commitment to fulfill His promises. Isaiah 62:1 affirms that for Zion's sake, God will not rest until His righteousness and salvation go forth. This demonstrates God's determination to save His people and His active engagement in the world to ensure that the Gospel reaches every corner. The preaching of the Gospel is the means by which God draws His elect to Himself, making it clear that His Word will not return void but will accomplish its purpose (Isaiah 55:11). Therefore, confidence in salvation stems from the certainty of God's promises and the efficacy of His Word.
